    Abstract: The present disclosure relates to an unlocking mechanism for a pistol magazine. Each of two release buttons is fastened to one end of a release lever controlling the translation of a lock cam arranged at the front or back of the handle. The lock cam includes a lock cooperating with an abutment surface arranged on the front or back surface of the magazine. A spring holds the lock cam in the lock position in the absence of pressure on the release button. Each release lever has a lug bearing on a corresponding lock cam lug of the lock cam. The lock cam is translated when one of the release buttons is actuated.
